A = 3.2 because -4.5 + 1.3 = 3.2
Equation A is linear and Equation B is nonlinear.
Equation A is linear bc it is a straight line, but B is a hyperbola which is ABSOLUTELY NOT LINEAR.
In the attachment below the red line is A and green is B
You divide both sides by 5 and then 2, leaving you with what the sum of x and y is.
Answer:
12 tapes and 20 CDs were sold.
Step-by-step explanation:
Since a music store had a sale on tapes and CDs, and tapes were on sale for $ 5 each and CDs were on sale for $ 7, and during the sale, 32 tapes and CDs were sold, and the cash receipts from the sale of the tapes and CDs, before taxes, were $ 200, to determine the number of CDs and tapes sold during the sale, the following calculation must be performed:
7 - 5 = 2
32 x 5 = 160
200 - 160 = 40
40/2 = 20
32 - 20 = 12
12 x 5 + 20 x 7 = X
60 + 140 = X
200 = X
Therefore, 12 tapes and 20 CDs were sold.
